When I get it, I will initially be trying it out for DSD audio. I will integrate it in with my Pioneer DV-989AVi which I modified for 2 channels only. I'll use the DAC in it to stream DSD. It has quite a reasonable BB DAC (PCM1738E) with an analogue stage that's been modified with OPA627's and 2SK170/2SJ74 complementary FET output.
Should be quite interesting.
I imagine the USBtoI2S board will have plenty of potential for upgrade tinkering, especially in the clock re-generators.
Hope to get it soon.
p.s. The board is available from this site too: http://jlsounds.com/products.html
Danny,
I'm not sure what you mean by 'regeneration' - it is just a synchronous re-clocking arrangement.
The big issue with these boards is they require galvanic isolation, but the isolators add jitter.
As such the clock needs to be DAC side of the isolator and a/ be sent back through the isolator
b/ re clock signals coming out of the isolator.
Also not sure which isolators they are using as there are quite a few different technologies
ATM all with various trade offs. Theoretically if the reclocking is done correctly this shouldn't
matter. We will see.
They appear to have done this correctly (I think). Then it's a case of types of clocks, logic
used for reclocking, bypassing, layout etc etc.
The price is pretty amazing for what they do - so I'm getting one.
cheers,
Terry
